UNllTElD STATES LETTERING PEN.

Application filed February 24, 1921.

T 0 all w/zmn it may concern Be it known that I, Vamps F. BARcH, a citizen of the United States, residing at lVashington, in the District of Columbia, have invented a new and useful Improvement in Lettering Pens or" which the following is a specification.

My invention relates to an improvement in lettering pens and has for its principal object the provision of a pen which will produce a uniform line regardless of the direction in which it is moved, which can be moved in all directions with equal facility and which will not blot or mar or scratch the surface of the paper when the pen is so moved and which can be easily cleaned.

A further object is to produce a pen of the type stated with substantially rigid nibs which are so shaped as to have an increased ink carrying capacity over the ordinary pen.

Other objects and advantages will be aparent from the following description. taken with the accompanying drawing which is by way of illustration only and not as a limitation of the invention, unless so limited in the appended claims.

Fig. 1 is a top plan view of the device, Figv 2 is an elevation and Fig. 3 is a bottom plan view. .Figs. 4: 5 and 6 are respectively top plan elevation and bottom plan views of the invention as applied to a smaller size pen. Fig. 7 is an elevation of a modifica tion showing the ink well in broken lines. Fig. 8 is a similar view of the modified form in a different position. and Fig. 9 is a plan view with the top nib in raised position.

1 is a pen having straight spaced nibs 2 and 3 drawn together at their ends t and 5 by screw 6, having a knurled head 8, which passes through upper nib 2 and has a threaded engagement with lower nib 3 in the conventional manner. The entire pen is firmly or detachably mounted on a shank 9.

The nibs are spaced one above the other in a vertical plane when the pen is in writing. position by the space 7. into which the ink is inserted and through which it flows down to the ends 4: and 5 as in an ordinary ruling pen and through which an ordinary sheet of blotting paper can be drawn to clean the pen.

The nibs 2 and 3 are substantially straight and terminate in semi-circular beveled ends 4 and 5. The ends t and 5 are beveled t0 the angle most convenient for writing and Specification of Letters Patent. Pafijgnihgqil Jung 1?, 1153322,

when brought near together form a flat circular writing surface which will form lines of equal width when moved in any direction. The rate of flow of the ink is regulated by adjusting the distance between the ends l and 5 through the medium of screw 6.

The ends of the nibs being beveled and perfectly smooth, the pen is easily and accurately guided over the surface of the paper in any direction without the scratching or blotting incident to the use or pointed lettering and ruling pens. And. the nibs being straight render the process of manufacture simpler, as the step to bending can be eliminated.

.ln pens of this character, especially those forming a broad line, which means the use of a larger quantity of ink per unit of length than for a narrow line. the carrying capacity of the nibs is not great enough to supply ink -for a long line, and it becomes necessary to refill the nibs at vtreo uent intervals. To overcome this difficulty. the improvement shown in Figs. 7 to 9 is used.

The pen shown in these figures is substantially the one described above with the following exceptions: Near the end of the lower nib 3 a. well 10 is formed. which may be of any shape at the end toward the shank 9. but which rises gradually to the surface of the nib a short distance back of the end 5, so that ink placed in well 10 will flow out in the direction of the end 5 by gravity. The upper nib 2 is shown as hinged at 11 on a pin 12 passing through the lower nib this hinge spaces the nibs so as to give the proper degree of resiliency when they are drawn together at the point by screw 6. and also allows nib 2 to be elevated or removed to permit the forming of well 10 during the process of manufacturing and to make subsequent cleaning easier.

I claim as my invention:

1. In a lettering pen the combination of two substantially rigid writing nibs spaced one above the other in a vertical plane when in writing position and substantially straight throughout their entire length. each nib having a semi-circular terminus and said nibs together forming a substantially circular writing surface.

2. In a lettering pen, the combination of abody portion two substantially rigid writing nibs spaced one above the other in a vertical plane when in writing position, each terminating in a semi-circular beveled plane and a thumb screw passing through said nibs for varying the width of said space.

8. In a lettering pen, the combination of two straight substantially rigid writing nibs, spaced one above the other in a vertical plane when in writing position each having a semi-circular beveled terminus and together forming a substantially circular writ ing surface, one of said nibs being movably connected with the other and means for holding the nibs together.

4. In a lettering pen, the combination of a body portion two vertically spaced substantially rigid nibs terminating in a substantially circular beveled plane an ink holding means formed in the lower nib and means for varying the width of opening between said nibs. a

5. In a lettering pen, the combination of a body portion two straight, vertical spaced, substantially rigid nibs, said nibs terminating in a substantially circular beveled plane marking surface, an ink holding depression formed in the top of the lower nib and a thumb screw with a knurled nut positioned above the upper nib, said screw passing through said nibs at right angles to said space to vary the width of said space.

6. In a lettering pen the combination of a body portion having two straight, vertically spaced, substantially rigid hinged nibs, the upper nib being hinged to the shank o1 the pen, said nibs terminating in a substantially circular beveled plane marking' surface, an ink holding depression formed in the upper portion of the lower nib, said depression rising gradually to the surface of said nib as it approaches the terminus of the nib and a thumb screw passing'through said nib at right angles to said space to vary the width of said space.

In testimony whereof I affix my signature.
